Chris,The cutting board is cut very close to the exact shape of the rod box. Then it is just slightly wedged into the carpet of the rod box (not extremely tight). Also, the 15 golf club tubes are pushed through the front and resting behind the cutting board to add a little stability. It is not mounted with any hardware, but it is very stable. It has not moved at all since I placed it about 6 months ago, and ive fished in some rough stuff several times. Hope that helps.KentKent Charles 2002 Pantera Classic & 200 Yamaha VMax
